Map and technical descriptions.
Article 40
ART. 40. Map and technical descriptions.—A map of the block desired to be explored shall accompany the application for Exploration Concession. This map shall be prepared in accordance with the Regulations, and shall show the location of the block with regard to the municipalities and province or provinces in which it is located, the four corners of the block in case it is rectangular, or the natural boundaries thereof in case the block adjoins rivers, creeks, Jakes, or shore lines, or the extension or projections thereof into these bodies of water in case the block is, in whole or in Part, on submerged lands. The location of the block shall be plotted on Coast and Geodetic Survey or Army base map, and shall show, among others, the topographic features of the area. The map shall be submitted together with the technical description of the corner markings and the metes and bounds or distances and bearings of the sides of the block. The technical description and map shall also indicate the bearings and distances of the tie line from some known reference location monument to one corner, preferably Number 1, of the block, in such a way that the block desired can be plotted from such tie line and descriptions on the Progress or Index Map of the Bureau of Mines, where all areas applied for shall be plotted to show the relative positions of such areas. The boundaries of the block desired shall be well established on the ground by placing permanent and conspicuous monuments, posts or mounds of earth on the corners, so that at any time, the block can be identified, and later be tied to accurate surveys. The bearings and distances of the block applied for exploration shall be sufficiently accurate so that the approximate area of the block can be computed from the given bearings and distances on the sides.
